Nowadays we use general purpose applications or libraries to communicate
with each other. For example, we often use an open source HTTP client
library to retrieve information from an open source web server and to
invoke a remote procedure call via web services.

In other words, Netty is a NIO client server framework which enables
quick and easy development of network applications such as protocol
servers and clients. It greatly simplifies and streamlines network

<title>Getting Started</title>
<para>
This chapter tours around the core constructs of Netty with simple
examples to let you get started with Netty easily. You will be able to
write a network application on top of Netty right away when you are at the
examples to let you get started quickly. You will be able to write a
client and a server on top of Netty right away when you are at the
end of this chapter.
